Title: Valve timing regulating device for internal combustion engine
Inventor: FUKAYA SHUNSUKE
IPC: F01L1/344
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provided a valve timing regulating device to regulate movement of a contact part in a non-constraint state, prevent the occurrence of collision of a contact part and the other member, and suppress the generation of strike noise. SOLUTION: In a way that a stopper piston 30 is fitted in a most lag angle position in a taper hole 34a, relative rotation between a shoe housing 11 and a vane rotor 14 is constrained. Oil pressure chambers 36 and 37 exert an oil pressure on the stopper piston 30 in a direction in which constrainment with the taper hole 34a is released. In the most lag angle position, a back pressure chamber 38 is communicated with an oil lubrication space 3a through communication passages 50, 51, and 52. When the vane rotor 14 is rotated from the most lag angle position toward the advance angle side based on the shoe housing 11, the pressure receiving area of the tip part 31a of the stopper piston 30 making contact with a hydraulic chamber 37 is decreased and communication between communication passages 50 and 51 is disconnected.  This constitution, since collision of the stopper piston 30 with the other member in a non- constraint state is suppressed, suppresses the generation of strike noise.
